The aim of the study was to report a clinical case of endodontic treatment of a maxillary first premolar with three root canals using an optical microscope and rotary instrumentation technique. The main complaint of the patient, a 16-year-old girl, was pain in tooth 14. After clinical and radiographic examination, irreversible pulpitis was diagnosed. An alteration in the middle third of the pul...

OBJECTIVE To investigate the anatomic symmetry of maxillary and mandibular posteriors in Indian subpopulation using cone beam computed tomography (CBCT). MATERIALS AND METHODS CBCT images of 246 patients that had at least one noncarious, posterior tooth free of restorations in each quadrant were enrolled for retrospective analysis. A total of 3015 teeth (811 maxillary premolars, 845 mandibula...

Objectives: The aim of this work has been a verification possibility to use 3D spin echo magnetic resonance imaging techniques in the dentistry within the scope of a dimensional imaging of the inner spaces of teeth during an prosthetic procedure. Methods: 6 extracted molar teeth were used after preparation for the inner root canals fixations. Magnetic resonance (MR) measurements were carried ou...

Lactobacillus, a part of the commensal oral microflora, is frequently found in infected root canals but is not considered to be an endodontic pathogen. Lactobacilli have proven to be difficult to identify on species level with biochemical and gene sequencing methods. MALDI-TOF is a new identification method and to our knowledge it has not been used on lactobacilli from infected root canals. The...

introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...

Mandibular canines present a complex internal anatomy. There are reported cases of canines with a single root and two canals, three canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a documented fact that clinicians should keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with ...

Purpose. The aim of this paper is to present cases of mandibular first molars with an additional distolingual root and their management using appropriate instruments and techniques. Basic Procedures and Main Findings. Mandibular molars can sometimes present a variation called radix entomolaris, wherein the tooth has an extra root attached to its lingual aspect. This additional root may complica...

OBJECTIVES The aim was to determine the success rate of single visit root canal treatment (RCT) and thus encourage clinicians to offer this treatment option appropriately. MATERIALS AND METHODS This was a longitudinal clinical study involving all teeth of the secondary dentition except third molars in the upper and lower jaws. Teeth having irreversible pulpitis, pulp necrosis or periapical pe...

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every...

The ultimate goal of endodontics therapy is the regeneration of tooth supporting tissues. This case study evaluated whether the transplantation of autologous dental pulp stem cells with chitosan scaffold into pulpless root canals could mediate pulp regeneration in human mature teeth. The dental pulp stem cells isolated from the patient`s pulp tissue. The cells were then seeded onto a chitosan s...
